Power Quality Analyzer Model 8230 616.3.4 Alarm Conditions ConfigurationThe Alarm Conditions window allows you to set up 10 alarm configurations.Figure 6-8Hysteresis: This value for alarms is set to prevent multiple recordings of an eventthat goes above the threshold and a certain percentage below it at times.Example: If the alarm threshold is 100V or higher, hysteresis is 1%. When the voltagegoes up to 100V, the alarm condition starts. When it goes back down to 99V, the alarmcondition stops.Schedule Alarm Search: When this check box is checked, an alarm is ready to bescheduled. Once checked, the End Alarm Search button will appear.End Alarm Search: This button will stop all alarms in progress.Capture Parameter: The alarm will be triggered based on the value of the selectedparameter.Choices include:• None: no alarm• Vrms: voltage root mean squared• Arms: current root mean squared• VPST: voltage short term flicker• Vcf: voltage crest factor• Acf: current crest factor• Hz: frequency• Akf: current K factor• Vthd: voltage total harmonic distortion• Athd: current total harmonic distortion• W: active power
